【问题2】
给六个部门分配完地址后，还有多少剩余地址，假设地址是从192.168.36.0开始分配的，请列出剩余地址段

答案

参考答案：

解析：剩余地址还有64个，剩余地址段是192.168.36.192～192.168.36.255。根据第一问得出的结论，我们可以知道，其中用了3位来做子网号，那么应该可以分配成8个子网，其中每个子网中有32个IP地址，从题目中我们可以知道，希赛公司有6个部门，其中每个部门分配一个子网，那么总共用去6个子网，还剩下两个子网，因此，在给6个部门分配完地址后，还剩余的地址数为2×32=64。 题目中告诉我们，假设地址是从192.168.36.0开始分配，那么总共分配掉的IP地址个数为6×32=192个，由于地址分配是从0开始的，那么分配192个地址后，下一个再分配的地址就应该从192开始，因此剩余地址段为192.168.36.192～192.168.36.255。
